Patented Sept. l'', 190'?.

To all 'whom it may concern:

Be it known that I, HUGO ,I-IAISS, a subject oi the Emperor of Germany,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and usefull Improvements inUniversal Beam-Frames, of which the following is a specification,reference being had therein to the accompanying drawing.

' This invention relates to universal beam irames, and the invention hasfor its object to provide a novel skeleton frame for concrete beams andgirders to add rigidity to them as well as to prevent sagging andcracking thereof. i j

` My invention aims to provide a metallic frame adapted to be embeddedin concrete beams or girders, the frames being constructed to equallydistribute in the beam the stresses and strains exerted thereon, thuspreventing shear stresses at the edges of; the supports. To

this end, I have devised a metallic skeleton trarne wherein a series ofbars or rods are arranged, locked together and anchored infa beam orgirder. The seriesA oi bars can be arranged in sets or be duplicatedaccording to the load of a beam or girder and as Well as its span orstretch. In some instances, Where the shear stresses are excessive, Iuse stirrups and stirrup spacing bars inconnection with the beam irarne,the stirrups being assembled in closer proximity to one another at theends of the beam, thereby preventing dislocation of the beam or girderdue to shear stresses` As a reinforcement Vfor beams and girders, theuniversal frame provides an anchorage to preventslipping of the barsembedded in the concrete, the reinforcement sustaining the entire weightof the beam or girder, thusproviding a beam or girder of considerablestrength and rigidity and tree from all danger of being dislocated byvibratory or constant load stresses.

The detail construction entering into my invention will be hereinaftermore fully described and then specifically pointed out in the appendedclaims.

Referring to thedrawing forming part of this specification, likenumerals of reference designate corresponding parte throughout theseveral views, in which:-

Fig. l2 is a side elevation, Fig. I3 is aperspective view oi the double frame lock, Fig. I4 is a plan ot a framelock illustrating twisted bars secured therein, Fig. l5 is an elevationoi' the same embedded in a concrete beamv or girder, Fig. l6`is a sideelevation of the same.

To put my invention into practice, I construct my improved beam orgirder frame o a plurality of parallel. rods or bars' l arranged in ahorizontal plane and maintained in this position parallel with oneanother by single irarne locks 2 and 3, said locks comprising barsthrough which the rods or bars l. extend. The frame locks 2 and 3 areprovided with depending supporting plugs 4 and with laterally projectingseparating plugs term as the end housings of a beam frame, while the o.The trame locks 2 constitute what I Willthereinafter locks 3 constituteintermediate housings, which are A' preferably located in closeproximity to the end housings on account oi the ends oi the concretebeam or girder being subjected to shearing stresses. lt will thereforebe observed that considerable space may exist between the intermediatehousings at one end or' a beam and the intermediate housings at theOpposite end, the amount oi space entirely depending upon the length andspan oi the beam. `The locks 2 and 3 and the rods or bars l iormpractically the foundation of ,a concrete beam or girder, and in orderythat the ends oi the rods or bars l can be 'firmly anchorgd in theplastic composition. oi the beam or girder, I provide the ends oi thebars or rods l with heads 16, which will also prevent slipping of saidbars in the concrete.

Upon the locks 3 oi the intermediate housings are secured by bolts andnuts 7, locks 8 and 9, the lock 8 housing rods or bars l0, While thelock 9 houses the rods or bars l0 and rods or bars Il, thus forming twolayers of lrods`or bars between the intermediate housings.

For supporting the ends of the vrods or bars l0 and Il, I provide thelocks 2 of: the end housings with rectangular shaped brackets l2, uponwhich ore iastened by nuts and bolts 14, locks l5, said locks receivingthe upwardly bent ends oi the rods and bars l() and 1I, the ends afterpassing through the locks l5 being parallel with the rods or bars I andprovided with heads I6. In elevating and anchoring the ends of the rodsor bars l0 and Il inf-the manner just described, there is less liabilityofthe centralportion oi the beam frame sag 'fing cr deiccting -thanwould be the case ii the ends ci the rods or bars 10 and Il remainparallel' escaso lboth iayers and supporting the bent ends of the rodsor 4mansversely-extending housings each embraeing ail of the rods orbars of lboth iayers, transversely-extending housings each embracing allof the rods or bars of the lower layer and some of the rods orbarsof theupper layer, the rods of the upper layer having the ends thereof bent inan angular manner with respect to the remaining portions of the rods,transverseyextending housings embracing the ends oi' the rods or bars ofboth layers-and supporting.l the' angular ends of the rods or bars ofthe 'upper layer in un eievated position with relation to theiowerlayer, said rods 'or bars having anchor ends.
